Cincinnati Zoo hopes it can save these special rhinos

Experts estimate there are fewer than 100 Sumatran rhinoceroses left on the planet -- perhaps as few as 30. If that's the case, 13 percent of all remaining members of this critically endangered specials trace their origins to a breeding program at the Cincinnati Zoo. "It's really a crisis we're facing," Terri Roth, a rhino reproduction expert, said after a recent trip to Sumatra. "The reports of the wild population, they're depressing, and there's no two ways about that." But the Cincinnati Zoo has contributed four new members to the declining population in the rhinos' native habitat. Andalas and Harapan, two male rhinos born at the zoo, were reintroduced to the wild later in life and are now part of an effort to bolster their species' numbers.
